BACKGROUND OF THE INVENTION Field of the Invention

Electronic cigarettes are quickly becoming a popular alternative to traditional cigarettes. With far fewer chemicals in the vapor produced by an electronic cigarette than the smoke of its more traditional counterpart and fewer restrictions regarding its use; their popularity is growing at a staggering rate.

The electronic cigarette acts as an inhaler that vaporizes a liquid solution, commonly known as an e-liquid, into an aerosol mist. This simulates the act of smoking when inhaled. This aerosol mist may appear to be smoke but is in fact just vapor. This means that the electronic cigarette can be enjoyed in many public areas.

It is common to customize the electronic cigarette sensation by using various liquids, often called e-liquids or juice. E-liquids are available in a wide range of different flavors, chemicals and strengths allowing the vapor to create different vaping experiences.

Of the various e-liquids available, many contain substances dangerous to children such as nicotine, Marijuana, or other toxic chemicals. Even though less than 5% of the public use e-cigarettes, they account for over 20% of poison center calls involving children under 5 years old according to the US Centers for Disease Control. E-cigarettes use is for adults, but the responsibility to protect children from their danger is up to the users. All containers holding e-cigarette components, including e-liquids, should include child-resistant closures.

Electronic cigarettes are made up of three major components: the battery, the atomizer, and the cartridge. The battery takes up a large portion of the unit and serves to power the electronic cigarette. The atomizer contains a heating coil which serves to vaporize liquid. It is usually set in the center of the electronic cigarette and consists of a wick which draws the liquid in. And finally, the cartridge serves as both the housing for the e-liquid and as the mouthpiece. The cartridge allows the passage of the liquid to the atomizer and subsequently the vapor from the atomizer to the user's mouth. The cartridge is designed to stop any liquid from leaking into the mouth.

This product improves other similar products. It is easier to use because it may be used with one hand while the other hand holds the vaping device. It has a non-removable child-resistant lid and is tamper proof. The product is smaller and thinner that similar products on the market.

Extensive research does not reveal any liquid container and dispenser specifically designed for vaping and e-cigarette use that combines the safety of unit construction (non-refillable), child-resistant containment, and ease of use. The product described herein is new and novel, and advances the state of the are in this field.
